Structure and luminescence properties of Dy doped quaternary tungstate LiBaGd(WO) for application in wLEDs.

Quaternary tungstates with the composition LiBaGd(WO) doped with different concentrations of Dy (from 0.5 to 10 at%) were prepared by the solid-state reaction method at 900 °C. Their structural, spectroscopic and optical properties were studied systematically in this work.
